Protozoans are classified based on the way that they move. Many Protozoans have advanced evolved Cilia (hair like fibers) or Flagella(a big tail) which help them move. Where others, such as, the amoeba use a pseudopodia to move around by stretching its cytoplasm âpullingâ itself forward to its next destination.
1 The first full-length episode of Oobi aired on April 7, 2003. Moose and Zee, Noggin's former hosts, were introduced on this same day.  Josh Selig, the creator of Oobi, was inspired to create the show after watching puppeteers in Poland perform with their bare hands.
One of the key sensors in this system is the oxygen sensor. It's often referred to as the O2 sensor because O2 is the chemical formula for oxygen (oxygen atoms always travel in pairs, never alone). The first O2 sensor was introduced in 1976 on a Volvo 240. California vehicles got them next in 1980 when California's emission rules required lower emissions.
